Notes: Plants eaten by deer (Martin et al. 1951). Allelopathic to competitors. Leaves and stems produce chlorogenic acid, ellagic acid and other phenolic compounds that inhibit nitrogen fixing symbionts in other plant roots (Rice, 1972). Plants often infected by the endophytic fungi Myriogenosporaatramentosa, Clavicipitaceae (Clay and Leuchtmann 1989). Infected plants may be very toxic due to alkaloids produced by the fungus. The fungus may infect inflorescences and render the plant sterile, later in the season these inflorescences produce small plantlets that carry the endophyte into the next generation (Clay 1990). Broom sedge is very similar to Schizachyriumscoparium (see below).
